TRAVELING VALVE.

Application filed May 10,

f barrel of an oil well;

A further object of the invention is the provision of packing which doesnot require a sleeve to hold it in place when the valve is beinginserted in the well tubing.

In the accompanying drawings, we have shown one embodiment of theinvention. In this showing:

Figure 1 is a vertical sectional View through 4the valve,

Figure 2 is a horizontal sectional view on line 2-2 of Figure 1,

Figure 3 is a similar view on line 3-3 of Figure 1, and,

Figure 4 is a similar view on line 1 -'4f of Figure 1.

Referring to the drawings, the reference numeral 1 designates a valvecage which is provided with a threaded projection 2 at its upper end,adapted to be secured to a sucker rod. A valve seat 3 is arranged at thebottom of the cage, the valve seat being removable as described in ourcopending application Serial No. 712,482, filed May 10, 192A A ballvalve l is arranged within the cage and adapted to engage the seat. Acylin drical member 5 is arranged beneath the cage, the upper end of thecylindrical member being provided with external threads adapted toengage internal threads formed on the lower end of the cage. This memberis provided with a flattened portion 6 for the reception of a wrench inassembling and disassembling the valve. Beneath the flattened portion,the cylindrical membery is adapted to receive suitable packingconsisting of packing rings 7 which, as shown, are substantiallyrectangular in cross section. These rings are arranged between lugs orshoulders 8 formed on the exterior of the casing and above the upperring, there is 1924. serial no. 712,4a1.

provided a shoulder having a beveled face 9. At the bottom of thecylindrical member, there is provided a cage 10` which extends upwardlyon the exterior of the casing and is provided with a beveled face llengaging the lower ring. Between the packing rings, there is providedspacing rings 12 which, as shown, are triangular in cross section,providing beveled or inclined faces 13, adapted to engage the packingrings.

The operation of the device will be apparent from the foregoingdescription. The valve is inserted in the well tubing in the same manneras the old style cup valve and the provision Qf a sleeve to hold thepacking while the valve is being run into the tubing is unnecessary. Thetraveling valve is reciprocated in the well tubing in the usual mannerby connecting the sucker rod to the upper end 2 of the cage.

It is to be understood that the form of our invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.

IVe claim:

l. In a traveling valve, a cage, a cylindrical member depending from thecage,

packing rings arranged on the exterior of said cylindrical member, andtriangular shaped spacing rings arranged between said packing rings withone face substantially parallel to theexterior of said cylindricalmember and with the edges of said face engaging the adjacent rings.

2. Ina traveling valve, a cage, a cylindrical member depending from thecage, said cylindrical member being provided with spaced lugs on itsperiphery, packing rings arranged between said lugs, and triangularshaped spacing rings arranged be tween said packing rings.

3. In a traveling valve, an upper cage, a ball valve arranged in saidcage, a cylindrical member depending from said upper cage, packing ringsarranged on the exterior of said cylindrical member, triangular shapedspacing rings arranged between said packing rings, with one facesubstantially parallel to the exterior of said cylindrical member andwith the edges of said face engaging the adjacent rings and a lower cageW rings arranged between said lugs, triangular shaped spacing ringsarranged over said lugs between said packing rings, and a lower Cagesecured to the bottom of said cylindri- Cal member and engaging saidlower packing ring.

In testimony whereof we aflix our signatures.
